I guess the next step are the lighter brakes. Interesting. On my car I have 2 sets, one for winter (15 inch) and one for summer (18 inch). 15 are 195/65 R15 and the 18 are 225/40 R18. The difference is huge when changing them. With the 15 it's very nimble.

Looks great, glad I came across this channel

I think that weight distribution will have greater effect than total weight of the wheel... 17" wheels = heavier tires, more weight at the outside, so the wheel has actually bigger momentum than 18" with lighter slimmer tire ?

Wax on, wax off... Mr miyagi knew his shit ^^ Been doing this since birth, and i have never got a loss against machine work vs my hands and patience & knowledge, nice car mate! Love these bigger e46's think im subbing, love that you put in some work and a eye for details 👌 / you'll never get a second chance for a first imression, so do it well, and you only have to do it once...SoOo- Swedish oldschool Oldggezer out ✌️and yeah, i get it, it's your daily, so Machine work is fine, i agree isch 😅

These things alone are a waste of time. You want a difference?, remap turbo + injector or bigger bore, or fit a bigger engine. That's the things that will make a noticeable difference...

Hi... I am thai. I am interesting in e46. Your VDO is very useful to learn to fix and maintenance. Thank you for you shared.

the steps...the KEY is the steps for that f1 sound !

Thank you very much for your job and your videos! I have a 330ci 5m with oem 2.93 diff; and i’m going to fit torsen blackline lsd with 3.38 diff from automatic, i have all the stuff in my garage…. hope that i’ll enjoy it. You’re great! i hope i have friend like you 😂 greetings from Italy

Brass sounds like how I expect the E46 to sound

A tip: if you tighten the rear shock absorbers on the lift with the wheels hanging, the rubber bearing on the shock absorber is fixed in this atypical position and permanently twisted to the maximum in everyday use. So just screw in the bolt and either lower the car completely and tighten it on the ground (uncomfortable) or lift the axle to the normal position with a gearbox jack.

The brass has a unique sound

i'm with you on the resonators + brass idea. I kinda preferred the tone of the brass as well even though the rasp was too much. This was a great experiment!

Very nice video! Maybe someone lets you borrow some racing lightweight wheels, l wonder if those can be felt

That brass sounds great

Great video , thank for your pedagogy... I own E46 320D Touring . Ten years ago I choose 205 55 R16 with 30mm spacers 60mm total . Bilstein B6 with Meyle HD . Racingdiffs LSD conversion Differential . Remap 180HP, 10 years later Hybrid Turbo stage 1 210HP . Looking at your rear axel restoration soon and Seksuspension Lift leveling kits too (snow) . Use that car to go work in ski station every winter days . What is your wheel alignment adjustment tool ?

good info, i always wonder if i upgrade to a larger rim, will it impact performance. logical thinking for sure it will but by how much is the question. now u proved it

How are you recording the acceleration test? If you have larger circumference wheel than another, this means the wheel speed sensor records less often than the smaller wheel, so the speedometer itself is not a fair test. This is also true comparing a worn tyre to a new one. The worn tyre will register a higher speed than the new tyre

your video is all over the place... and boring production, but the idea is good 😢

I lovee the way brASSEXhausts sound

Damn very nice Video, thanks a lot for all the work you put into this!

Thanks for this work dude! But the other question is, or should be? In my case choosed to go bigger, from 16 to 17", but about 2KG each rim lighter, how does it effect? (because I heard that even lighter rims will be a bad choise because of the lever arm and diameter), did this do fit a bigger Brake. But all in all I would suggest, that you would not notice a big real deal between this, 0,1-0,2 sec "faster" is nothing saying about the conditions at all, like you said, 3 ° Celsius can make a small difference, the road condition, the measurements can have tolerance, and so on. So people have to take a look on the weight of their rims, but not but it because only of the weight... thank you, maybe I will "rethink" and stay with good OEM wheels, should also fit more to the sleeper build than crying for attention

Yo use oxy acetylene to wash the weld a or get like a htp America welder with a cooler for “cheap” probably still around 1000$-1600$ American but got entry level none the less that can run off any wall outlet so if you do end up spending some money you can do some side jobs basically anywhere very easily to pay it off and if you think you need one with slot of features look up a miller dynasty 200 or miller maxstar 200x and they are old and beat up who cares spend 1000 on the box and 1000 to rebuild it or splurge the new one for work looking like 18000$

Y mounted style 94 on my E39 with bridgestone potenza 245/35/18 , 22kg wheel and tire , before the ugly style 48 with 225/55/16 ; the ride its a total difference , much better in corner and those tires a just perfect , y live in the french Pyrénées (border with spain) with a lot of cornering , much safer , with 4 sachs and springs for option S227A M sport

I tried to talk to wheel to spec but the wheel gave me a silent treatment what should I do?

this is fantastic, i have a set of these in my storage unit next to the e36 & finding stuff like this gets me foaming at the mouth to get back to it. Sick stuff here!

I saw a comment below and took offence, where a guy said basically that OEMplusResto was just some guy trying to make money "there are not many channels on the internet where they speak english and show you a video how to save money! We have all been their "do i get B4s or B8s and or even B16s, what are the differences in terms of handling and reliability? What springs should i get, and after you have decided you still look for comparisons due to the financial costs inolved for the layout! OEMRestoplus has saved me about " £1500, but the most important the lack of knowlege i had the actual comparisons when fitted and seeing the differences to then wanting to do the job myself! 💯BMW Gentleman

Were you flooring it?

The compound is very different from the first 17inch tyres I prefer 18 inch myself cause my 118i is like a go cart to drive now Next this you could do is try the pu bushes on the swaybars 👌🏾 I did mine with the red one it's 10 times better than the stock ones Now when I turn the wheel it reacts right away no delay no spungy feeling I like it

you mentioned the 18s feeling much tighter and precise in the corners, "on rails", would you say the handling benefits are worth the acceleration sacrifices?

Nice test. I noticed you filled the tank with 95 octane. Maybe the acceleration improves when you put 98 octane or V-power in the car. The throttle response is better when I use V-power in my 530i. I didn't measure the acceleration so it is perhaps more psychological than actual increase. Btw I think the grey rims look better on your car. But that is just my personal opinion.

I prefer the style 68 wheels.. Sits nice.

Good work

If you must wonder about smaller rims and tyres, your car is definitly to wake😂

And now please test the maximum speed in curves with this shit small tires against the 255ers😜

On ya mate! Every vid you do is gold. As a long time e46 guy, those little differences you dig into tend to be things I wondered about, also. Thank you for making such a stellar effort, and sharing it with us...

La differenza e schiacciante con cerchi superleggeri R17(14kg) rispetto ai 18 "originali" (23kg)

You should use oz ultraleggera 17" and see if there are

Excellent video my friend. Very informative and answered all the questions I had. I'm curios about brass

If I remember correctly the styling 32 are among the lightest original wheels. By the way unsprung mass = four times sprung mass. Saving 1kg on a wheel equals saving 4kg on the (for example) cars body...

What about for 2007 z4?

Lets boost algorithm for our man here, this channel should be a lot bigger. Only useful real life tests

Apparently powerflex also creates Z4M polyurethane bushings for in E46's. Would be cool to see 😉

On the wheel/tire calculator website, you measured the new setup as 19” instead of 18” so your values are off more because of this error

Great video. I purchased some 18x9.5 TE37 and put some 265 35 tires. They weight 5 lbs, which I think is just over 2kg per corner less than my style 68s. My 330 didn't feel quicker but I can take turns way faster. I didn't realize the difference until I put my style 68s back on and the car felt sluggish on acceleration. I didn't test into great detail like you did though. Great video.

I think welding brass kills its sound

Very easy, no complications: Top speed german autobahn ( better stability and brake ): 18" Continental SportContact 7 or Goodyear F1 Super Sport ( Summer ) Other use ( better feedback power steering ): 17" Michelin Sport 4 or Bridgestone Potenza Sport ( Summer ).

Flot bil😊

it's amazing all the work that you put in your videos just to do scientific tests, and i really enjoy it. It is very interesting to watch and gives me many answers to many questions. Thank you !

a lighter wheel configuration will reduce fuel consumption, which is also important for those who want to save a little and for those with weaker motors, this option will reduce the load on the motor.
